Introduction

Product Features

The Dell®_{Managed Rack Power Distribution Unit (PDU) is a stand-alone,}

network-manageable power distribution device. The Rack PDU provides real-time remote monitoring of connected loads. User-defined alarms warn of potential circuit overloads. The Rack PDU provides full control over outlets through remote commands and user interface settings.

You can manage a Rack PDU through its Web interface, its command line interface (CLI), or Simple Network Management Protocol (SNMP):

• Access the Web interface using Hypertext Transfer Protocol or using secure HTTP (HTTPS) with Secure Sockets Layer (SSL). See Logging On to the Web Interface. • Access the command line interface through a serial connection, Telnet, or Secure

Shell (SSH). See About the Command Line Interface.

• Use an SNMP browser and the Dell Management Information Base (MIB) to manage your Rack PDU.

Rack PDUs have these additional features:

• Peak load, and power and energy monitoring for all connected loads. • Voltage, current, and power monitoring for phases.

• Power monitoring for each outlet.

• Configurable alarm thresholds that provide network and visual alarms to help avoid overloaded circuits.

• Four levels of user access accounts: Administrator, Device User, Read-Only User, and Outlet User.

• Up to twenty-four independent outlet user accounts.

• Event and data logging. The event log is accessible by Telnet, Secure CoPy (SCP), File Transfer Protocol (FTP), serial connection, or Web browser (using HTTPS access with SSL, or using HTTP access). The data log is accessible by Web browser, SCP, or FTP.

• E-mail notifications for Rack PDU and system events.

• SNMP traps, Syslog messages, and e-mail notifications based on the severity level or category of the Rack PDU and system events.

• Security protocols for authentication and encryption.

Access priorities for logging on

Only one user at a time can log on to the Rack PDU. The priority for access, beginning with the highest priority, is as follows:

• Local access to the command line interface from a computer with a direct serial connection to the Rack PDU

• Telnet or Secure Shell (SSH) access to the command line interface from a remote computer

• Web access

The Rack PDU does not provide power surge protection. To ensure that the device is protected from power failure or power surges, connect the Rack PDU to an uninterruptible power supply (UPS).

Types of user accounts

The Rack PDU has four levels of access (Administrator, Device User, Read-Only User, and Outlet User), which are protected by user name and password requirements. • An Administrator can use all of the menus in the Web interface and all of the

commands in the command line interface. The default user name and password are both admin.

• A Device User can access only the following:

– In the Web interface, the menus on the Device Manager tab, the Environment

tab, and the event and data logs, accessible under the Events and Data headings on the left navigation menu of the Logs tab. The event and data logs display no button to clear the log.

– In the command line interface, the equivalent features and options. The default user name and password are both device.

• A Read-Only User has the following restricted access: – Access through the Web interface only.

– Access to the same tabs and menus as a Device User, but without the capability to change configurations, control devices, delete data, or use file transfer options. Links to configuration options are visible but disabled. The event and data logs display no button to clear the log.

The default user name and password are both readonly.

• An Outlet User has the following restricted access:

– Access through the Web interface and command line interface.

– Access to the same menus as a Device User, but with limited capability to change configurations, control devices, delete data, or use file transfer options. Links to configuration options are visible but are disabled. The Outlet User has access to the Outlet Control menu option that allows the user to control the outlets assigned by the Administrator. Outlet Users cannot clear the event or data logs.

The user name and password are defined by the Administrator during the process of adding a new Outlet User.

Getting Started

To start using the Rack PDU:

1. Install the Rack PDU using the Rack Power Distribution Unit Installation

Instructions that were shipped with your Rack PDU.

2. Apply power and connect to your network. Follow the directions in the Rack

Power Distribution Unit Installation Instructions.

3. Establish network settings. (See Establishing Network Settings.) 4. Begin using the Rack PDU by way of one of the following:

• Web Interface

• Command Line Interface

Establishing Network Settings

You must configure the following TCP/IP settings before the Rack PDU can operate on a network:

• IP address of the Rack PDU • Subnet mask

• Default gateway

TCP/IP configuration methods

Use one of the following methods to define the TCP/IP settings needed by the Rack PDU:

• BOOTP and DHCP configuration

• Command Line Interface

If a default gateway is unavailable, use the IP address of a computer that is located on the same subnet as the Rack PDU and that is usually running. The Rack PDU uses the default gateway to test the network when traffic is very light.

BOOTP and DHCP configuration

The default TCP/IP configuration setting, DHCP, assumes that a properly configured DHCP server is available to provide TCP/IP settings to Rack PDUs. You can also configure the setting for BOOTP.

A user configuration (INI) file can function as a BOOTP or DHCP boot file. For more information, see Use an .ini File.

BOOTP. For the Rack PDU to use a BOOTP server to configure its TCP/IP settings, it must find a properly configured RFC951-compliant BOOTP server.

In the BOOTPTAB file of the BOOTP server, enter the Rack PDU’s MAC address, IP address, subnet mask, and default gateway, and, optionally, a bootup file name. Look for the MAC address on the bottom of the Rack PDU or on the Quality Assurance slip included in the package.

When the Rack PDU reboots, the BOOTP server provides it with the TCP/IP settings. • If you specified a bootup file name, the Rack PDU attempts to transfer that file from

the BOOTP server using TFTP or FTP. The Rack PDU assumes all settings specified in the bootup file.

• If you did not specify a bootup file name, you can configure the other settings of the Rack PDU remotely through its Web Interface or Command Line Interface.

DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the Rack PDU.

1. The Rack PDU sends out a DHCP request that uses the following to identify itself:

• A Vendor Class Identifier

• A Client Identifier (by default, the MAC address of the Rack PDU)

• A User Class Identifier (by default, the identification of the application firmware installed on the Rack PDU)

2. A properly configured DHCP server responds with a DHCP offer that includes all the settings that the Rack PDU needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). The Rack PDU can be configured to ignore DHCP offers that do not

encapsulate the vendor cookie in DHCP option 43 using the following

hexadecimal format. (The Rack PDU does not require this cookie by default.)

Option 43 = 01 04 31 41 50 43

Where:

• The first byte (01) is the code. • The second byte (04) is the length.

• The remaining bytes (31 41 50 43) are the vendor cookie.

This section summarizes the Rack PDU’s communication with a DHCP server. For more detail about how a DHCP server can configure the network settings for a Rack PDU, see DHCP response options.

Command Line Interface

1. Log on to the command line interface. See Logging on to the Command Line Interface.

2. Contact your network administrator to obtain the IP address, subnet mask, and default gateway for the Rack PDU.

3. Use these three commands to configure network settings. (Text in italics indicates a variable.)

a. tcpip -i yourIPaddress b. tcpip -s yourSubnetMask c. tcpip -g yourDefaultGateway

For each variable, type a numeric value that has the format xxx.xxx.xxx.xxx. For example, to set a system IP address of 156.205.14.141, type the following command and press ENTER:

tcpip -i 156.205.14.141

4. Type exit. The Rack PDU restarts to apply the changes.

Recovering from a Lost Password

You can use a local computer (a computer that connects to the Rack PDU or other device through the serial port) to access the command line interface.

1. Select a serial port at the local computer, and disable any service that uses that port.

2. Connect the provided serial cable to the selected port on the computer and to the Serial port at the Rack PDU.

3. Run a terminal program (such as HyperTerminal®) and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.

4. Press ENTER, repeatedly if necessary, to display the User Name prompt. If you

are unable to display the User Name prompt, verify the following: – The serial port is not in use by another application.

– The terminal settings are correct as specified in step 3. – The correct cable is being used as specified in step 2.

5. Press the Reset button. The Status LED will flash alternately orange and green. Press the Reset button a second time immediately while the LED is flashing to reset the user name and password to their defaults temporarily.

6. Press ENTER, repeatedly if necessary, to display the User Name prompt again, then use, dell, for the user name and password. (If you take longer than 30 seconds to log on after the User Name prompt is redisplayed, you must repeat step 5 and log on again.)

7. At the command line interface, use the following commands to change the User Name and Password settings, both of which are now dell:

Command Line Interface

About the Command Line Interface

You can use the command line interface to view the status of and manage the Rack PDU. In addition, the command line interface enables you to create scripts for

automated operation. An Administrator has full access to the command line interface, a Device user and Outlet user have limited access, and a Read-Only user is completely restricted. (For additional details, see Types of user accounts.)

You can configure all parameters of a Rack PDU (including those for which there are not specific CLI commands) by using the CLI to transfer an INI file to the Rack PDU. The CLI uses XMODEM to perform the transfer. However, you cannot read the current INI file through XMODEM.

Logging on to the Command Line Interface

To access the command line interface, you can use either a local (serial) connection or a remote (Telnet or SSH) connection with a computer on the same network as the Rack PDU.

Remote access to the command line interface

You can access the command line interface through Telnet or SSH. Telnet is enabled by default. Enabling SSH disables Telnet.

To enable or disable these access methods, use the Web interface. On the

(21)

Telnet for basic access. Telnet provides the basic security of authentication by user name and password, but not the high-security benefits of encryption.

To use Telnet to access the command line interface:

1. From a computer on the same network as the Rack PDU, at a command prompt, type telnet and the IP address for the Rack PDU (for example, telnet

139.225.6.133, when the Rack PDU uses the default Telnet port of 23), and

press ENTER.

If the Rack PDU uses a non-default port number (from 5000 to 32768), you must include a colon or a space, depending on your Telnet client, between the IP address (or DNS name) and the port number. (These are commands for general usage: some clients do not allow you to specify the port as an arguement and some may require extra commands.)

2. Enter the user name and password (by default, admin and admin for an Administrator, or device and device for a Device User).

SSH for high-security access. If you use the high security of SSL for the Web interface, use SSH for access to the command line interface. SSH encrypts user names, passwords, and transmitted data. The interface, user accounts, and user access rights are the same whether you access the command line interface through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client program installed on your computer.
